One human, two customer records, two commerce systems

FitGrill runs WooCommerce and Heartland with different catalogs, plus Como. The same person orders $30 through one and $30 through the other. Whether the platform sees one customer or two is an ingestion question with no documented answer, and it decides whether this is a Qualified Referral.

Look at: The disagreement here is about the facts, not the rules, so the two rows are two different ledgers under identical program terms.

The readings

Same rules, different facts

No identity resolution

Each commerce system's customer id is taken at face value, so two records of $30 never reach the threshold.

Same rules, different facts

Identities resolved to one customer

A shared customer key across systems collapses the two records, and $60 of qualifying spend produces a referral.
